We have selected a standard task through a decision step. In order for the task to retrieve the responsible agents, we are using a role. The role returns a list of pernrs, that become the responsible agents.
All these agents can then access the task through a web inbox we have developed. This web inbox is sending the pernr of the user as parameter, and retreiving the tasks assigned to that pernr.
Until here, everything works fine
The problem is that from time to time (no pattern so far), when the workflow gets initiated, and the decision workitem is created, there is an empty agent together with the list of pernrs. If I manually execute the role, the list of pernrs is the right one, but when I look into the workflow log, the first line of the responsible agents is an empty row.
The main problem is that it seems that this empty row has the task "reserved" as nobody else can see that specific task in their inboxes
Do you have any idea/suggestion why this may be happening?
Thanks in advance for your comments,
